( #3333=superdoc: print w/replies, xml ) Need Help??
thanks all. I went with the following based on your feedback -
use strict; my @targets = ('', '', '', ''); my @list = intermix( @targets ); use Data::Dumper; print Dumper \@list; sub intermix { my @list = @_; my %hash; # separating hash my @ret; # returning list # build hash structure, each similar first 3 octects as key # array reference w/ IP addresses as values for (@list) { push( @{ $hash{ substr($_,0,rindex($_,'.')) } }, $_ ); } my @keys = keys %hash; while (@keys) { push(@keys, shift(@keys)); # rotate keys # extract one element, or delete the array ref and try again my $item = shift @{$hash{ $keys[0] }} || shift @keys && next; push @ret, $item; } return @ret; } __END__ $VAR1 = [ '', '', '', '' ];
This doesn't require a specially defined sequential list type. I'm sorry it doesn't look small and neat though.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
